A few days after the LG Optimus L9 began receiving the official update to Android 4.1.2 Jelly Bean in Europe, it’s now the turn for LG Optimus 4X HD and Optimus L7 owners to rejoice. In a blog post, LG Germany announced that both devices will be receiving the software upgrade by the end of this month. Granted, there’s an “Important Note” in the post stating that the vague schedule may be pushed, and any device with network operator branding may have to wait longer for approval processes by the network carrier to get done.

The update won’t be available over-the-air, and users will need to use the LG Mobile Support Tool to download and install it. It is recommended that you backup all your data on your device first before going through with the update. You can find the full download and installation instructions in the original blog post (in German) here.
